The lawsuit, filed on Thursday in Los Angeles Superior Court, says that the company helped the reality star earn a hefty paycheck after a successful first season of Jersey Shore. Pauly D and ICM had a verbal agreement that entitled the company to 10 percent of DelVecchio's business opportunities. After getting 10 percent commission for the MTV show's second season, ICM was fired by Pauly D, but now claims it is owed subsequent profit totaling $370,000 for the past two seasons of the series.

"[There's a] standard custom and practice in the entertainment industry that talent agencies are entitled to post-termination commissions on all deals they negotiate for their client," the agency said. "No deed goes unpunished, however, and DelVecchio ultimately terminated the representation."

Pauly D denies that he owes ICM any money. "We are surprised by ICM's contention that it is due commissions after ICM was terminated in favor of William Morris Endeavor," his lawyer, Hillary H. Hughes, said in a statement. "ICM was paid for its services. It is even more disappointing that an agency like ICM would choose to take advantage of its former relationship with a client and disclose his confidential business affairs to the public in disregard of any duties it owes as a talent agency."
